数学简便计算1.35×0.27-13.5×0.007要怎么算？

Answer 1

1.35×0.27-13.5×0.007
=1.35×0.27-1.35×10x0.007
=1.35x（0.27-0.07）
=1.35x0.2
=0.27

Answer 2

1.35×0.27一13.5X0.007
=1.35X0.27一1.35Ⅹ10Ⅹ0.007
=1.35X（0.27一10Ⅹ0.007）
=1.35X（0.27一0.07）
=1.35X0.2
=0.27

Answer 3

1.35×0.27－13.5×0.007
＝1.35×（0.27－0.07）
＝1.35×0.2
＝0.27

Answer 4

1.35×0.27－13.5×0.007
=1.35×(0.27－10×0.007)
=1.35×(0.27－0.07)
=1.35×0.2
=0.27
